i'm sceptical about time travel too and i think it's rather sci-fi based, but again, i would like to refer to a Michael Crichton book, "Timeline," which talks about the possibility of traveling into one of the infinite parallel universes where the timeline is different. i see that as somewhat sci-fi too, and while parallel universes may exists, i'm very sceptical about the possibility of traveling between them. we'd have to consider a load of paradoxes linked to our human paradigm of perception (btw, i love paradoxes)
on a sidenote, michael crichton's books are very interesting and engaging, but i don't find them very stimulating, because he writes in a "hollywood" style - aka heroes who never die, and too much drama overall. but he does make valid scientifical statements which are well-researched. |

has anyone read the novel Timeline from Michael Critchton? (also being made into a movie) If i remember correctly, there was no such thing as time travel, but the ability to travel to a universe where time was "recorded", and the way to reach that universe was to turn into energy, which u lost ur physical form and in a sense, kills u, only to use that energy to build you in the other universe |
haha, you beat me to it :p |

Sounds to me like the gravitys just having some strange effect on ur watch. Surely the hands would find it difficult to turn under such pressure.
How does anyone know that time looks slower if ur going at the speed of light?
And these worm holes. If u went outside the universe u would simply be in an inescapable vacuum. How can the universe be folded?
I dont believe any of this time warping at all. Just sounds a bit far fetched. But it is interesting. |
It doesn't have to be a mechanical watch. :rolleyes: Anyway, it has been proven that time dilation exists in accelerated systems. An airplane was launched with an atomic clock (a very precise non-mechanical clock, just so you don't think acceleration had any effect on its dials), travelled at high speed for a while, and when it landed, the two clocks showed different time.
As soon as you get outside the atmosphere you're already in an inescapable vacuum. But the universe is folded wherever a gravitational field exists. Einstein proved it by observing a solar eclipse in early 20th century. The stars that were behind the eclipsed sun had their relative distances messed up in comparison to when they were observed without a strong gravitational field in between.

It sounds like some people r saying u can actually do to make the world start acting like somebodys rewinding a tape.
How can time be physical? What form exactly would it take? |
Physical doesn't mean a 3d material object. :rolleyes: Time exists, time is quantifiable, it has relations with other physical processes and is therefore a physical quantity. No insult, but you should read some elementary high school physics books. |

you forgot to mention that they had a second clock that they left on the ground that showed the exact same time before the other one was launched. |

It is physically impossible to travel at the speed of light look at it this way fighter pilots wear anti g suits and the new one they have out can handle up to 9 g's on turns and acceleration durring these a pilots blood is pushed toward the lower half of his body this sudden shift in blood volume away from the brain can cause a blackout and if you hit mabey about 14 g's your gone now imagine taking off in a jet lets say you cant just right away boom light speed you would instantly die you would have to gradually get up to the speed of light and that would take a lifetime there is no way ever a human will EVER travel at the speed of light, the speed of light is 299,792,458 meters per second
Anyone seen Donnie Darko |

(this is a little back there but...
ok what about E=mc^2, if it takes an infinate amount of energy to travel at the spead of light and c is constant doesnt that make M increase? |

I know. I havnt read any :D
Still cant get my head round WHY or how time could possibly be going at different speeds. And im too tired to think about it now |

| it's amazing that all these people have extensive schooling in the area of time travel! who knew? |

yeah your right.
mass = 1/sqrt(1-v^2/c^2)
amazing isn't it even ME! i guess we're all show-offs now |

so that means along with slowing down you also gain mass
so that dude is a much younger fatty twin?
:crazy: |

| i heard this wild theory that at extremely high acceleration rates time actually goes FASTER for you, as opposed to the theory of relativity. interesting. |

At 1 g it would take you little less than a year to accelerate to that sort of speed. One year has 31536000 seconds, and if you were to accelerate at 1 g, your speed at the end of the year would be about 9.81*31536000, or a little more than the speed of light. |
